* [PATCH v6 0/9] Dynamic RSS Configuration for Bonding

OVERVIEW
--------
1) Setting .rxmode.mq_mode for bonding device to ETH_MQ_RX_RSS makes bonding
device fully RSS-capable, so all slaves are synchronized with its configuration.
This mode is intended to provide RSS configuration as known from "dynamic RSS
configuration for one port" and made slaves transparent for client application
implementation.

2) If .rxmode.mq_mode for bonding device isn't ETH_MQ_RX_RSS, slaves are not
synchronized. That provides an ability to configure them manually. This mode may
be useful when application wants to manage RSS in an unusual way and the
consistency of RSS configuration for slaves isn't required.

Turning on/off RSS mode for slaves when bonding is started is not possible.
Other RSS configuration is propagated over slaves, when bonding device API is
used to do it.

v6 changes:
 - patchset reordered
 - fixed forward dependency between patch 4/9 and 5/9

v5 changes:
 - updated to DPDK 2.2
 - removed copyright change from null device source
 - removed queue_stats_mapping_set from eth_dev_ops of bonding device
 - null pmd cleanups (removed unnecessary malloc, replaced memcpy with
   rte_memcpy)
 - fixed queues number configuration in null pmd

v4 changes:
 - fixed copy-paste error,
 - removed example application as too complex and introducing a new
   dependency,
 - addapted null pmd to be used as testing device for dynamic RSS configuration,
 - addapted test units to use null pmd instead of ring pmd,
 - ring pmd is not used and changed in this patchset

v3 changes:
 - checkpatch cleanups

v2 changes:
 - added support for keys other than 40 bytes long,
 - now, if RSS key is not set for bonding, it is not set also for slaves,
 - fix - full initial RSS configuration before any slave is added was not
   possible due to the initially zeroed flow_type_rss_offloads for bonding,
 - fix - changed error to warning when slave is synchronizing due to the
   bonding's initial configuration (to allow use slaves' drivers not supporting
   dynamic RSS configuration in bonding),
 - some code cleanups,
 - updated documentation,

Tomasz Kulasek (9):
  bonding: rss dynamic configuration
  null: fix segfault when null_pmd added to bonding
  null: extend number of virtual queues
  null: export eth_dev_null_create
  null: virtual dynamic rss configuration
  test: dynamic rss configuration
  bonding: per queue stats
  doc: fixed spellings and typos
  doc: dynamic rss configuration for bonding
